Hey I was wandering how you can use electricity to build muscle. I heard that Bruce Lee did this… Does anyone know anything about it?

You’re probably talking about EMS. No, you really can’t “build muscles”, not the way you’d like at least, and the ads for these things are jokes of course, but EMS does have its uses for athletes and even for bodybuilders. Charlie Francis has written a very detailed article on this topic for T-mag. We’ll publish it in a few weeks.
